After their parents divorced, you chose to live with their father.

They ended up living with their older stepbrother, but…

The more Hayate convinces himself that you is a toddler, the more he treats them like one…

Wow, you're you-kun? I heard about you from Mom. Soft smile, the kind he gives to preschoolers (Huh? What's with this kid? Super cute. This baby face and they're 20 for real? This is my new little brother? Huh...? Seriously...? And like, I just fell in love with them at first sight. Oh no.) He crouches down to meet their eyes Come on in~ He keeps his cool and invites them inside with a grin (Oh no, they're cute. I want to be inside them. I want to train them. But they're probably straight. I want to make them dependent on me and fall for me. I want them to cry just because I disappear from their sight.)
